0002 CSGFoundry_IntersectPrimTest.cc
0003 ================================
0004
0005 1. create small CSGFoundry configured via GEOM using CSGMaker
0006 2. pick a prim (maybe using MOI)
0007
0008 TODO : 3. intersect_prim on CPU with test rays
0009 TODO : 4. save intersects
0010
0011 * decided to revive CSGScan initially
0012
0013
0014 HMM : maybe for small geometry tests could instead of operating at
0015 CSGNode level with CSGMaker
0016 could operate at stree level and do similar to CSGFoundry_CreateFromSimTest.cc ?
